[TLI] Add prototype checking for all remaining LibFuncs. This is another step towards unifying all LibFunc prototype checks. This work started in r267758 (D19469); add the remaining checks. Also add a unittest that checks each libfunc declared with a known-valid and known-invalid prototype. New libfuncs added in the future are required to have prototype checking in place; the known-valid test will fail otherwise. Differential Revision: https://reviews.llvm.org/D28030 llvm-svn: 292188

Update the file headers across all of the LLVM projects in the monorepo to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

[Analysis] Add LibFunc_ prefix to enums in TargetLibraryInfo. (NFC) Summary: The LibFunc::Func enum holds enumerators named for libc functions. Unfortunately, there are real situations, including libc implementations, where function names are actually macros (musl uses "#define fopen64 fopen", for example; any other transitively visible macro would have similar effects). Strictly speaking, a conforming C++ Standard Library should provide any such macros as functions instead (via <cstdio>). However, there are some "library" functions which are not part of the standard, and thus not subject to this rule (fopen64, for example). So, in order to be both portable and consistent, the enum should not use the bare function names. The old enum naming used a namespace LibFunc and an enum Func, with bare enumerators. This patch changes LibFunc to be an enum with enumerators prefixed with "LibFFunc_". (Unfortunately, a scoped enum is not sufficient to override macros.)

Creating a named struct requires only a Context and a name, but looking up a struct by name requires a Module. The method on Module merely accesses the LLVMContextImpl and no data from the module itself, so this patch moves getTypeByName to a static method on StructType that takes a Context and a name. There's a small number of users of this function, they are all updated. This updates the C API adding a new method LLVMGetTypeByName2 that takes a context and a name.

[opaque pointer types] Add a FunctionCallee wrapper type, and use it. Recommit r352791 after tweaking DerivedTypes.h slightly, so that gcc doesn't choke on it, hopefully. Original Message: The FunctionCallee type is effectively a {FunctionType*,Value*} pair, and is a useful convenience to enable code to continue passing the result of getOrInsertFunction() through to EmitCall, even once pointer types lose their pointee-type. Then: - update the CallInst/InvokeInst instruction creation functions to take a Callee, - modify getOrInsertFunction to return FunctionCallee, and - update all callers appropriately. One area of particular note is the change to the sanitizer code. Previously, they had been casting the result of `getOrInsertFunction` to a `Function*` via `checkSanitizerInterfaceFunction`, and storing that. That would report an error if someone had already inserted a function declaraction with a mismatching signature. However, in general, LLVM allows for such mismatches, as `getOrInsertFunction` will automatically insert a bitcast if needed. As part of this cleanup, cause the sanitizer code to do the same. (It will call its functions using the expected signature, however they may have been declared.) Finally, in a small number of locations, callers of `getOrInsertFunction` actually were expecting/requiring that a brand new function was being created. In such cases, I've switched them to Function::Create instead. Differential Revision: https://reviews.llvm.org/D57315 llvm-svn: 352827

Introduce support for lib function aligned_alloc in TLI / memory builtins Aligned_alloc is a standard lib function and has been in glibc since 2.16 and in the C11 standard. It has semantics similar to malloc/calloc for several analyses/transforms. This patch introduces aligned_alloc in target library info and memory builtins. Subsequent ones will make other passes aware and fix https://bugs.llvm.org/show_bug.cgi?id=44062 This change will also be useful to LLVM generators that need to allocate buffers of vector elements larger than 16 bytes (for eg. 256-bit ones), element boundary alignment for which is not typically provided by glibc malloc.

[Analysis] Support AIX vec_malloc routines This is to support the memory routines vec_malloc, vec_calloc, vec_realloc, and vec_free. These routines manage memory that is 16-byte aligned. And they are only available on AIX. Differential Revision: https://reviews.llvm.org/D94710

[TLI] Add prototype checking for all remaining LibFuncs. This is another step towards unifying all LibFunc prototype checks. This work started in r267758 (D19469); add the remaining checks. Also add a unittest that checks each libfunc declared with a known-valid and known-invalid prototype. New libfuncs added in the future are required to have prototype checking in place; the known-valid test will fail otherwise. Differential Revision: https://reviews.llvm.org/D28030 llvm-svn: 292188

[Analysis] Add LibFunc_ prefix to enums in TargetLibraryInfo. (NFC) Summary: The LibFunc::Func enum holds enumerators named for libc functions. Unfortunately, there are real situations, including libc implementations, where function names are actually macros (musl uses "#define fopen64 fopen", for example; any other transitively visible macro would have similar effects). Strictly speaking, a conforming C++ Standard Library should provide any such macros as functions instead (via <cstdio>). However, there are some "library" functions which are not part of the standard, and thus not subject to this rule (fopen64, for example). So, in order to be both portable and consistent, the enum should not use the bare function names. The old enum naming used a namespace LibFunc and an enum Func, with bare enumerators. This patch changes LibFunc to be an enum with enumerators prefixed with "LibFFunc_". (Unfortunately, a scoped enum is not sufficient to override macros.) There are additional changes required in clang. Reviewers: rsmith Subscribers: mehdi_amini, mzolotukhin, nemanjai, llvm-commits Differential Revision: https://reviews.llvm.org/D28476 llvm-svn: 292848
